To all whomawzg ooh-corn." Be it known that l, l l lLLlelii E. luowLER,

Ilia, residing at Mount Lebanon, in the county of Allegheny end; Stateof Pennsylo voriie, s. citizen of the United States, have invented ordiscovered certain new and use- ;tul leiprovements in Securing BralwBeampports to Trocks, of which omprovements the following; is ospecification.

The invention described herein relates to the, class or type of devicesknown inthe art es brake beam supports, which are usedos auxiliaries tothe hangers to maintain the brake shoe Whether in contest with thetrcatl of the Wheel or in normal position in proper concentric positionrelative to the wheel and to ensure the pr er application otthe brakeshoes regardless hin limits of the i1an1cter ot the \vhccls. hosesupports consist of one i two spring b Whether'thc broke beam is to besupported oi two points in azlclitionto the usipil hangers, and a shoeor shoes IDtCIPOSG(l between the brake beam and the rail or rolls.Prefcrobl v and in most cases the rail or rails are secured to thespring plank of the truck oncl on account of the position of the springplank relative to othc parts of the. truck Eliliicultv is encountered inso attacliiu r the rails which extend on both sides oi the spring plankin such moi-loci? as will perm t of the easy removal and replsccmeut ofthe mils when repairs are necessary.

The invention described herein relates to certain ii'nprovemcnts in therhczor er of ettoching the rails described and claimed iii :inapplication filed February 28, 192%, by Broderick Haskell, Serial No.695,795, which consists, generally stated, in forming the rail. with aportion adapted to he passecl ougli on opening in the spring plank andidiiig means whereby the portion proi through the opening is prevented noccidental withclmwal. The improvehereinafter more fully describedilull. claimed.

lo the accompanying drawings forming; a port of this specification, Fig.1 is a plan zieir showing a portion of the spring-plank of e truck and asupporting mil secured to the plank in the ma'nner claimed. herein; li is: 2 and 3 are sectional views 01. "lanes i-eoicotecl respectively bythe lines 3..lI----II s or roils,'(lep ci1clent uponv serial No. motel.

end fil -ill, Fig. ii; Figs. eleml 5 are views similar to ldigs. 1. and.2 illustrating omodification of the improvement; Fig. 6 is 1). viewsimilar to Fig. 5 illustrating a znodificition of the improvement; andlg. 7 is a sectional View on a. plane imlicetecl by the line Vll-Vlll.

lo the practice oi the invention the supporting rail extends across thespring plank lend projects a. sufiicierit distance on each side of thespring plank to underlie the terision members 2 of the brake beam. Theend portions 3 of the rail are so bent as to'heve an upward inclinationwhen the rail is secured to the truck and. on these portions 3 are moi'sbly mounted blocks or shoes 4; heyiiog seats 5 for the tension members2. The shoes-ore held as against occidental. move oieiit ofi of therails by shoulders L which are conveniently formed by heeded rivets,

shown The intermeclietc portion of the rail is so bent that the railwill beer on the pleiik only at points adjacent to the edges of theplank as 'inclicetccl id, such bearing portioos having sufficient lengthto reirieio. in contact with the pistol: duringpermissibleioiigitudiriel movements of the rail. *The means employed forconnecting the rail to the plank ct point intermediate the hem ings Gare so constructed that the portions intermediate the seats must bedeflected from normal before such connection can be cliectecl. lo theconstruction shown herein the means employed to attach the rail to theplank consists of 9. loop or Ushapecl portion .'Z oppositely inclinedresilient portions 8 ex tending from the loop to the bearings (3, saidloop being passed through. on opening in the spring plank and held inposition by a' lacy or pro.

y reference to Fig. 2 it Will be seen that the portions 8 Will when thebearings 6 contact with the plank, be inclined away from the plank andthe loop is made of such a height that the portions 8 must be.cleflectccl 15 locking" pin 10 on the opposite side.

shoulders 11 adapted to bear against opposite edges of the opening 9 toprevent its longitudinal movement out of the loop. The opening throughthe spring plank is made of v 5 such a width relative to the length ofthe opening in the plank and prevent such 1on gitudinal movement of therail as will move 10 the bearings 6 out of contact with the plank.

It is characteristic of the described construction that the rail hasthree points of bearing on the spring plank, i. e., the bearings 6 onone side of the plank and the rail or at least the portions of the railintermediate the bearings 6 are resilient.

As is well known in the art, the spring plank may be formed by channelbars 1 as shown in Figs. 1, 2 and 3, or by spaced angle bars 1, as shownin Figs. 4 and 5.

When the plank is formed of angle bars the supporting rail is attachedto a plate 12 extending across the gap between the angle bars andriveted or otherwise secured thereto.

When applying the support rail above the 'spring plank, which can bereadily done when the plank is formed with narrow or low flanges, theportions of rail intermediate the inclined portions carrying the shoesand the loop 7 are made straight as shown in Figs. 7 and 6, the lowfianges 13 of the plank 1 operating to perform the function of thebearings 6 in the construction shown in Figs..1 to 3, of so supportingthe middle portion of therail in which the loop is located in suchposition that port-ions mu'fst be deflected in order to permit of therail being locked to the plank. By reference to Figs. 1 and 2 it will beseen that by the employment of a shoe hav; ing an open-topped seat orsaddle, the brake beam can be placed or replaced in position withoutchanging the position of the sup porting rail which carries the shoe,and also that the supporting rail and shoe can be placed in positionwithout changing the connection of the brake beam with the truck andwithout changing either the shape of the shoe or its manner ofconnection with the supporting rail.

It is characteristic of'the construction shown and described herein thatas the shoes are freely movable along the supporting'rziils and that thetension member can slide freely along the seatsor saddles of the shoesthe brake beam is free to move at all times in directions at an angle toand parallel with the supporting rails and thus automatically adjustitself to operative position.

I claim herein as my invention: 1. The combination of a truck elementand a supporting rail having spaced bearings on one side of the truckelement, and a The bearing on the opposite side of the truck element,the latter bearing being intermcdt ate of and spaced from the otherhearings.

2. The combination of a truck element and a supporting rail having apoint intermediate its ends connected to the truck element and havingpoints spaced from sucli point of connection bearing resiliently on thetruck element.

3.
